The NotifyIcons NuGet package versions enumerated have been flagged for containing malicious code as per the OpenSSF malicious packages database. This is a supply chain threat where compromised package versions may execute unauthorized or harmful actions when used. The advisory does not provide technical details on the nature of the malicious code or exploitation methods. No patch or remediation guidance is provided, and the package is not a cloud service, so remediation depends on users avoiding or removing these specific versions.

Users who install or depend on the affected NotifyIcons package versions risk executing malicious code embedded in these versions. This could lead to compromise of the development environment or downstream applications that consume these packages. No confirmed active exploitation has been reported, but the presence of malicious code inherently threatens integrity and security.

Avoid using the listed affected versions of the NotifyIcons package. Since no patch or fixed versions are provided, users should remove these versions from their dependencies and replace them with versions not listed as affected or alternative packages. Monitor vendor or community advisories for updates or official remediation.
